Overheating RAM despite low temperatures?
Overheating RAM despite low temperatures?
These are DDR5 memory settings at 4800 MHz. The RAM has successfully passed Memtest86 tests with no problems, so everything looks good. The 50°C temperature is normal for this type of setup.
The labels on the display are up-to-date, low, high, average, correct. That suggests you're not currently running at a high heat level, likely during your test. High temperature and overheating are different concepts; the latter is usually shown in red to distinguish it from hardware info. A GPU will reduce performance based on heat and mark it as 'high', but that doesn't confirm overheating.
Can you understand those numbers? The voltage looks a bit strange when reading it. I mentioned RAM passed Memtest86, there were no freezes, BSODs, or file corruption—so why do my CPU temperature and voltage readings show "external part twisting"?
Your performance metrics seem unusual. At 50°C you don’t see the usual "high temp" warning, and there’s no throttling when the temperature nears 89°C. Your board might be overheating because of weak VRM or inadequate airflow.
Activating the EXPO profile for your RAM changes its performance characteristics, likely reducing its speed to match the stock rate.
I’m going to treat this as a possible issue, not a real problem. The PMIC in most DDR5 chips often gives inaccurate readings and shows odd behavior—like reporting a temperature around 63°C even when it wasn’t near that value. With the extremely high VIN voltage it displayed, it seems likely the issue was just a glitch in the reporting.
I steer clear of temperatures above 50°C unless I can handle it directly or just run at very high heat. This is because I use high-frequency, high-voltage overclocks where excessive heat causes issues, and weaker connections degrade faster at slower speeds like 4800. In stable tests it should be fine, but 4800 is slow—does it come with a heat spreader? If yes, enabling XMP will help it run at its rated speed instead of underperforming.
Readings seem incorrect, I'm using a 6000 Kit but turned off EXPO because it's causing issues. It doesn't work in OS, and restarting the PC gets stuck during DRAM memory training. I've disabled EXPO completely now. Neither turning it on nor off showed any errors in Windows or gaming.
Seems like you're considering the same thing, but I'm not sure if it's an issue since your board has VRAM heat sinks. The model is ASUS Tuf B650 Plus WIFI.
